FAN-OPERATING MEANS.

i A'pp'lication filed September 27, 1922. Serial No.590,994.

To all whom it may concern.- Be it known thatl, *ARVID F.-CARLIN, a

citizen of the United States, and a resident of Mamaroneck, in the county of WVestchester and State of New York, have invented certain new and useful Improvements in Fan-Operating Means,of which the followa ing is a specification.

' Thisinvention has reference to means for operating a fan that will be actuated by pulling on a cord whichcan extend some dis t ance from the device.

The object of the invention is to provide "an improved device of "this character that fwill' produce the rapid, rotation of a fan by merely pulling on a cord or cable, and

' which is assistedby a spring that is wound up when the cord is pulled and will serve to rewind the cord when released, and the fan 'will continue to" rotate through the rewinding.

A fu'rther'ohject is to provide means to cause the fan while rotating to swing through an are back and forth, andwhich will turn in one direction when the cord is tion. r

Fig; 6 shows separatelythe'pawlg- Fig. 7 showsin detail the loop and gear. Most of themechanism is mounted in a 4:0

casing 2"in which rotates the main shaft 3 projecting fronrthe front of the casing and this shaft in the casing carries the reel 4 fast thereto. A coil spring 5 has one end* fast to thesh aft 3, andthe other end secured to'a pin .6 on the, casingand' a cord or cable 7-passes' in through the. opening in the'bottom of the casing and is" secured to the reel and wound around the reel, so that when the cord is pulled and unwound'toturn the reel inione'direction, it willrotate the shaft 3 and wind up thecoilfspringl When the cord is releasedthe springwillu'nwind and again windiup the cord bymotati'ng the reel and I on the shaft 3* is loosely mounte a gear 4; on this shaft.

pawl and ratchet wheel, mounted respec increased speed.

wheel 8, that engages a pinion 9 fast on a spindle 10 at the upper part of the casing, and to which spindle is secured the fan 11. This shaft 10 rotates in the front plate 12 of the casing and is also supported by a bent arm 13 that extends out from the cylindrical shell 14 of the casing.

,Means are further provided to connect the gear 8 with the shaft or with the drum This isin the form of a tively on these two members. As shown in Fig. 4 the pawl 15 is pivoted on the reel at, which engages the ratchet wheel 16'fast to the gear 8. These two members are so arranged that when the reel rotates in one direction by pulling on the cord, the ratchet wheel will engage the pawl and cause rotation of the gear 8; which latter through the pinion 9 will rotate the fan shaft 10 at an But when the cord is released and the coil spring now under tension will rotate the reel in the opposite direction,

the ratchet wheel will engage the pawl to turn the gear in this direction. When the cord rotates the fan shaft rapidly the fan 1 will acquire a suitable momentum by this high speed, and this reversed movement of the ratchet wheel, will permit the gear turn- -ing in the opposite direction free to be r0- tate'cl by the fan. The cord will be rapidly wound up by the coil spring since very little energy is required during which time the fan will continue to run, thenthe cord 1s again pulled out and the ratchet wheel will again engage the pawl and gear to give a fresh impulse. By this means the rotating of the fan shaft is practically continuous.

The casing 2 as shown is movable on a support 20 in the form of a bent arm. The rear wall 2 of the casing has apertured ears 22 and 23 at the top and Bottom, and the car 22 is pivoted by a rivet 24L in the bent portion 28 of the arm. The lower car 23 is pivoted by set screw 25 on abent portion 26 of the support 20, that isjin alinement with the pivot '25 and permitsthe casing to swing on these pivots in a lateral direction. But when the said screw 25 is tightened the cars 'ing is locked against swinging and made fast on the arm20. 'At the lower end of the arm 20 is a swinging guide-pulley 27 V for the cord.

position by means of a bracket 30, having of the rack teeth, when it can continue torotate. :tending to start a 100 92 inthe reverse di-;

rection, when it reaches each end portion of apertured arm 31 on the bottom through which extends the lower reduced end 32 of the bracket support 20. At the upper end of the bracket 30 is an arm 33 having a long slot 34 to receive a bolt 35' carried by the upper bent end 36 of the support 20. A

wing nut 37 on the bolt 35 serves to lock the upper end of the support 20 in adjusted positions. In Fig.1, the casing and support are shown to incline but when the wing nut is loosened the casing can be moved in toward the bracket 30 to any position in the slotted arm 33 and thenlocked in such posi, tion by the wing nut.

7 Means are provided foriswinging the cas ing on the support that are connected with 7 the main shaft 3. Abar 40 extends upward from the support 20 and carries a rack plate 41, that is engagedby a form of pinion or gear 42 on the end of shaft 3. This device is preferably in the form of a. wire loop 42, see Fig. 5, that'serves when the shaft 3 rotates, to engage its two parallel portions between the teeth of the rack 41, and this will operate to advance the loop andshaft along the stationary rack- 41. It has been 7 set forth that the shaft 3 turns in one direction when the cord is pulled and in the opposite direction when released and the spring winds up the cord. This will cause-the shaft to' move up in one direction along the rack when the cord is pulled andin .the

opposite'direction' when the shaft 3 is re- 25.:V6IS6Cl. When this loop 2 reaches one end of the rack 41 it will be permitted to continue turning in the same direction because of a space at 43 between the last tooth and an extension 44 of the rack At the other end of the rack is a similar space 45 adjacent an upright projection 46. It will be under-. stood that shifting of the shaft 3 will move thejcasing 2 that carries the fan shaft, that .is will swing on the pivots at 24, and 25.

lVhenthe cord is pulled the rotation of the shaft 3 will turnthe casing until the loop 42 reaches one end of the rack and the cas ing will not swingvfurther, but theshaft 3 Q willjcontinue to rotate as long as the cord is pulled. Release of the cord will cause i the shaft 3 to rotate in theopposite direc% tion by the coil spring unwinding and the.

k loop 42 will now turn in the opposite direc tion and will. travel across the rack and swing the casing and fan at the opposite end But it is desirable to provide means therack bar. For thispurpose I provide plate springs 44 and 45 on the support 20 at the rear of the casing, seeFig. .3. -"Ihese will be placed in tension as thecasing is turned, and when the "'sha-ft3 is reversed willtend to move the shaft in theoppo'site direction of travel and start the loop 42 in a What I claim is: i

Similar springs 47 and 47' are provided on the rack bar 41, that will directly engage the shaft'3 for the same purpose. m

both directions at this place and cannot be moved by the spring. I

It will be seen fromliigs. 4, 5 and 6, that the pawl 15 isin the form of adouble pawl provided with an arm 60. Thispawl has an ear 61'that projects under a bent ear 62 of .the reel .4. The ar-m l5 of the pawl rides under a bent car 63 on the reel '4, that eX- tends over this projecting end 64. The arm 60, or the arm 15 will: fall 'intothe ratchet wheel 16 by gravity and cause the ratchet wheel to turn the gear. 8,?when the string is pulled. But when the spring rotates the ratchet wheel in the opposite direction it will force out the engaging .pawl end and permit the gear 8'to rotate freely. I
